Question

Mr Avalon's cousin's Kurt and rod started their own business curtain rods curtain rods they sell curtain rods for $5 each they rent a store in the mall for their business for $2,500 per month how many curtain rods must they sell to earn a profit of$ 3750?​

Answer 1

1,250 curtain rods

Step-by-step explanation:

2500 + 3750 = 6250

6250/5=1,250

1,250 curtain rods

Answer 2

Answer:34.3 N and 15.7 N

Step-by-step explanation:

= force on the left end of the rod

= force on the right end of the rod

M = mass of Halloween decoration = 3 kg

= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N

m = mass of rod = 2.1 kg

= weight of the rod = mg = 2.1 x 9.8 = 20.6 N

From the force diagram, using equilibrium of torque about A

(AB) + (AC) = (AD)

(29.4) (21) + (20.6) (57) = (114)

= 15.7 N

Using equilibrium of force along the vertical direction

+ = +

15.7 + = 29.4 + 20.6

= 34.3 N
